INTRODUCTION
The National Pollutant Discharge Elimination System (NPDES) permit program is a
requirement of the federal Clean Water Act. The federal Environmental Protection
Agency (EPA) has delegated permit authority to state environmental agencies. In
Washington, the NPDES delegated permit authority is the Washington State Department
of Ecology (DOE).
This document was prepared by the City of Tukwila to meet the requirements for a
Stormwater Management Program (SWMP) Plan as required by the NPDES Phase II
Permit. The SWMP Plan was developed to reduce pollutant discharges from the City's
Municipal Separate Storm Sewer System (MS4)
The Permit allows discharge of stormwater runoff from municipal drainage systems into
the state's water bodies (i.e., streams, rivers, lakes, wetlands, etc.) as long as
municipalities implement programs to protect water quality by reducing the discharge of
"non -point source" pollutants to the "maximum extent practicable" (MEP). In addition,
the City must meet "all known and reasonable treatment" (AKART) through application
of Permit specified "best management practices" (BMPs). The practices specified in the
Permit are collectively referred to as the SWMP Plan and grouped under the following
program components:
Public Education and Outreach
Public Involvement and Participation
Illicit Discharge Detection and Elimination
Controlling Runoff from New Development, Redevelopment and Construction
Sites
Pollution Prevention and Operation and Maintenance for Municipal Operations
Coordination
Compliance with Total Maximum Daily Load Requirements
Monitoring and Assessment
The Permit requires that the City:
Report annually (by March 31 of each year) on the SWMP Plan implementation
from the prior year.
Submit annually (by March 31 of each year) a SWMP Plan that describes
proposed surface water management program activities for the coming year.
Develop a SWMP Plan that includes an ongoing program for gathering, tracking,
maintaining, and using information to evaluate its SWMP Plan development,
implementation and permit compliance and to set priorities.
Coordinate with other permittees on stormwater-related policies, programs, and
projects within adjoining or shared areas.
Coordinate with City departments to eliminate barriers to compliance with the
terms of the permit. Include a description of coordination in the Annual Report no
later than March 31, 2015.

NPDES PHASE II PROGRAM COMPONENTS
Tukwila is defined as a Phase II community by DOE and, therefore, mandated to comply
with the requirements of the Phase II National Pollution Discharge Elimination System
(NPDES) Stormwater Permit. Phase II communities are those that:
Own and operate a storm drain system
Discharge to surface waters of the state
Are located in urbanized areas
Have a population of more than 1,000
Municipalities with a population of over 100,000 (as of the 2010 census) have been
designated as Phase I communities and must comply with DOE's Phase I NPDES
Municipal Stormwater Permit. Tukwila's population is below the 100,000 threshold and
must comply with the Phase II Municipal Stormwater Permit. Approximately 100 other
municipalities in Washington must now comply with the Phase II Permit, as operators of
small "municipal separate storm sewer systems" (MS4). Ecology's Phase II Permit is
available on Ecology's Web site at:
http://www. ecy.wa. gov/programs/wq/stormwater/municipal/phaseIIww/wwphiipermit.html
Tukwila completed requirements of its initially issued NPDES Phase II Stormwater
Permit which expired July 31, 2013. Tukwila applied to the Department of Ecology and
was issued a new five-year term NPDES Phase II Stormwater Permit on August 1, 2012
with an effective date of August 1, 2013 and an expiration date of July 31, 2018. The
Permit was then modified and reissued December 17, 2014 with an effective date of
January 16, 2014 to further control the discharge of pollutants to protect surface water
and ground water quality in Washington State.
As stated, the major program components listed in the Permit are as follows:
Public Education and Outreach
Public Involvement and Participation
Illicit Discharge Detection and Elimination
Controlling Runoff from New Development, Redevelopment, and Construction Sites
Pollution Prevention and Operation and Maintenance for Municipal Operations
Coordination
Total Maximum Daily Load Requirements
Monitoring and Assessment
The following sections describe requirements of each program component, the City's
current activities, and what the City's planned activities are to meet the requirements. In
general, the City of Tukwila is currently performing all previously required NPDES
Phase II Permit activities and has programs in place to address the updated Permit
requirements.

City of Tukwila
Stormwater Management Program Plan 10 of 13 March, 2015
The City uses a formal process by distributing a routing slip to ascertain each
department has the opportunity to assign appropriate staff for review of each
proposed project.
Development review meetings occur weekly, where permit requirements are
identified. Review meetings are attended by the NPDES Coordinator,
Development Engineers and other key staff
Externally, City projects that impact interconnected MS4s are coordinated on an
informal basis. Staff coordinates with WSDOT, King County, Kent, Renton,
Burien and Sea Tac.
Private property projects that will connect to a neighboring City's storm drainage
facility are referred to that particular City for approval.
SEPA is an additional mechanism used to coordinate with other jurisdictions.
The City's stormwater map is made available to those jurisdictions with
interconnected MS4s.
All efforts are made by the City to play an active role in various NPDES regional
coordination groups. An NPDES contact list which includes both Phase I and
Phase II Permittees is maintained and updated when necessary.
In addition, the Tukwila's Operations and Maintenance performs a lead role
interacting internally and with neighboring jurisdictions with physically
interconnected MS4s. A contact coordination list is maintained and updated as
necessary.
6.3 Planned Activities
Coordination efforts include:
The City will continue coordination efforts internally and with neighboring cities
and jurisdictions.
Issue an internal memorandum of mandated NPDES updates ensuring each
department understands the Permit requirements.
Provide a gap analysis to determine specific coordination needs.
Summarize this year's Coordination efforts in the Annual Report.
7. COMPLIANCE WITH TOTAL MAXIMUM DAILY LOAD REQUIREMENTS
The Permit (Section S7) requirements apply if an applicable Total Maximum Daily Load
(TMDL) is approved for stormwater discharges from MS4s owned or operated by the
Permittee. Applicable TMDLs are TMDLs which have been approved by EPA on or
before the issuance date of this Permit or prior to the date that Ecology issues coverage
under this permit, whichever is later. A TMDL is a calculation of the maximum amount
of a pollutant that a water body can receive and still safely meet water quality standards.
The DOE determines the reduction of pollutant discharge needed to be compliant with
water quality standards. A TMDL has not been established for the City of Tukwila at this
time, consequently no action needed.
